Pull-up resistors on I2C?

Can someone tell me if the TX2 module already has on-board pullups for I2C (and to which voltage), or if I should add those externally? What would be the correct value of resistor to add here?

Edit: To be clear: I’m talking about the module, and NOT the dev kit.

Well, in case anyone else comes looking for an answer to this, I’ve confirmed with a meter that SDA and SCL lines are pulled up to 3.3v (at least on I2C_1).

Hi, you can also get the answer from I2C chapter of OEM DG. https://developer.nvidia.com/embedded/dlc/jetson-tx2-tx2i-oem-product-designguide

Perfect, thanks!
